'Whenemployed in admixture with soap and soda ash this 'colloidal clay exhibits two important features; first it greatly increases the bulk of the owder, second, it increases the detergent e ect of the same more than would an equal addition of .eithergsoap or soda ash. Accordingly the advantageous effects of this substance are most conspicuous in connection with those soap powders having minimum percentages of soap, owing to the fact that the increased bulkiness is most effective under these conditions, and also I owing to the fact that the feflfect of the clay is more apparent when the amount of soap is already small. This enables a package of given size to be made and sold more cheapl or a'given amount of cleansing effect to secured by smaller weight of material, or' a' larger quantity of thepowder to be furn ished for a given price, depending upon the choice of the manufacturer.

Having thus described my invention what I claim is:
